Hi;
I need a simple guide for customizing Spark and creating an installation package of my own to deploy.
My requirements are:
- Change UI images/colors/fonts to match Company theme.
- Remove menu items/tabs/buttons... etc as needed and keep only those required.
- Change whatever needed in installation package so that only branded and customized installation works with Spark server (not even the downloaded Spark from web).
I'm not a developer 
so a nice, simple, and step by step from scratch guide/video.....etc would be highly appreciated.
Thanks in advance.
